CURRENT MOTOR.

Application filed February 10, 1926. Serial No. 87,247.

This invention relates to an improved current motor which is located so as to receive the impact of waves or the flow of the current, and the invention is designed to Withstand the strains that such a structure is subjected to inasmuch as the operating and associated parts are supported on piles and in turn act to .brace and support the said supporting piles. 1 i The invention is designed to provide compact and smoothly running motor and one which can contain, if desired, an electric or other motor which transforms the power received from the motor. The invention is illustrated in the accompanying drawing in which Figure 1 is a vertical section of a motor made according to my invention and Figure 2 is a section on line 22 in Figure 1.

As a foundation or support for the device, I arrange piles 10 and the preferred form is to arrange them in circular spaced relation and I place a support around the piles so that it embraces and also braces them.

In the form shown, this support comprises a cylinder 11 whichis tightly fitted over the piles so that the parts are in contact but it will be evident that fastening means may be employed if desired.

I refer to this supporting element as the fixed cylinder and surrounding it and spaced therefrom is a rotatable cylinder 11 which is freely rotatable and to insure a free 'rotation I arrange the rollers 12 so that they rotate on the cylinder 11, the cylinder 11 being usually provided with the tracks 13. one for each set of rollers, and in order to bear the weight of the rotatable cylinder and to prevent its being forced downward, I provide rollers 1 1 arranged in the head 15 of the To table cylinder and running on a track 16 in the head 17 of the fixed cylinder. To pre vent upward thrust of the rotatable cylinder I provide the rollers 18 which run on the track 19 on the cylinder 11.

Blades or paddles are placed on the rotatable cylinder, these blades being shown at 20 and being arranged tangentially thereon so as to form the pockets 21, these blades being thus adapted to receive the full force of the waves or the current and forming but slight resistance in passing around in a direction against the influence of the waves or current.

In order to more firmly brace the piles and to provide if necessary a chamber for the installation of an electric motoror other form of motor, I place a drum 22 inside of the piles and snugly fitted in the spaces between the piles, the bearings 23 on the head 17 and the bearings 24 in the partition 25 of the drum firmly supporting the shaft 26.

The shaft 26 is secured by any suitable connection 27 to the head of the rotatable cylinder. The shaft 26 is thus used to drive an external or outside motor or transformer of any kind or the motor can be placed in the chamber 28 of the drum which in this case, of course, would necessitate the closing of the drum 22 at the bottom if such motor or transformer required a water-tight compartment. Such a closure is shown in dotted lines at 29 in Figure 1. v

l/Vhile I have described cylindrical members throughout, it will be evident that in the bracing members and also in the drum, the shape can be changed to conform to any other arrangement of piles'than that shown, to meet unusual or peculiar conditions.

I claim:

1. A current motor comprising a circular set of piles, a cylinder secured on the piles and enclosing them, a rotatable cylinder surrounding the fixed cylinder a'nd having rollers disposed so as to permit only rotary movement of the rotatable cylinder, and tangential blades secured on the outside of the rotatable cylinder.

2. A current moton comprising'a circular set of piles, a cylinder secured on the piles and enclosing them, a rotatable cylinder surrounding the fixed cylinder and having rollers disposed so as to permit only rotary movement of the rotatable cylinder, tangential blades secured on the outside of the rotatable cylinder, and a drum fitting inside the set of piles and a shaft supported in bearings on the drum and secured to the rotatable cylinder.

3. A current motor comprising a group of spaced piles, a structure embracing and bracing the group of piles and including circular tracks, av rotatable member surrounding the above associate parts and having rollers to run on the tracks, and blades arranged on the outside of the member.

In testimony whereof I aifix my signature.

ALEXANDER VVHITTLE.
